finalizepsbt

Finalize the inputs of a PSBT. If the transaction is fully signed, it will produce a network serialized transaction which can be broadcast with sendrawtransaction. Otherwise a PSBT will be created which has the final_scriptSig and final_scriptWitness fields filled for inputs that are complete. Implements the Finalizer and Extractor roles.

Arguments

  If true and the transaction is complete, extract and return the complete transaction in normal network serialization instead of the PSBT.

Returns

]
}

fundrawtransaction

Add inputs to a transaction until it has enough in value to meet its out value. This will not modify existing inputs, and will add at most one change output to the outputs. No existing outputs will be modified unless "subtractFeeFromOutputs" is specified. Note that inputs which were signed may need to be resigned after completion since in/outputs have been added. The inputs added will not be signed, use signrawtransaction for that. Note that all existing inputs must have their previous output transaction be in the wallet. Note that all inputs selected must be of standard form and P2SH scripts must be in the wallet using importaddress or addmultisigaddress (to calculate fees). You can see whether this is the case by checking the "solvable" field in the listunspent output. Only pay-to-pubkey, multisig, and P2SH versions thereof are currently supported for watch-only

Arguments

  string
  The hex string of the raw transaction
• options

The fee will be equally deducted from the amount of each specified output. The outputs are specified by their zero-based index, before any change output is added. Those recipients will receive less bitcoins than you enter in their corresponding amount field. If no outputs are specified here, the sender pays the fee. [vout_index,...] "replaceable" (boolean, optional) Marks this transaction as BIP125 replaceable. Allows this transaction to be replaced by a transaction with higher fees "conf_target" (numeric, optional) Confirmation target (in blocks) "estimate_mode" (string, optional, default=UNSET) The fee estimate mode, must be one of: "UNSET" "ECONOMICAL" "CONSERVATIVE" } for backward compatibility: passing in a true instead of an object will result in {"includeWatching":true}

getrawtransaction

NOTE: By default this function only works for mempool transactions. If the -txindex option is enabled, it also works for blockchain transactions. If the block which contains the transaction is known, its hash can be provided even for nodes without -txindex. Note that if a blockhash is provided, only that block will be searched and if the transaction is in the mempool or other blocks, or if this node does not have the given block available, the transaction will not be found. DEPRECATED: for now, it also works for transactions with unspent outputs. Return the raw transaction data. If verbose is 'true', returns an Object with information about 'txid'. If verbose is 'false' or omitted, returns a string that is serialized, hex-encoded data for 'txid'.

It has no effect on transactions which are already abandoned.

Arguments

• txid
  string
  The transaction id

abortrescan

Stops current wallet rescan triggered by an RPC call, e.g. by an importprivkey call.

addmultisigaddress

Add a nrequired-to-sign multisignature address to the wallet. Requires a new wallet backup. Each key is a Bitcoin address or hex-encoded public key. This functionality is only intended for use with non-watchonly addresses. See `importaddress` for watchonly p2sh address support. If 'label' is specified, assign address to that label.

Arguments

• nrequired
  number
  The number of required signatures out of the n keys or addresses.
• keys
  string
  A json array of bitcoin addresses or hex-encoded public keys [ "address" (string) bitcoin address or hex-encoded public key ..., ]

bumpfee

Bumps the fee of an opt-in-RBF transaction T, replacing it with a new transaction B. An opt-in RBF transaction with the given txid must be in the wallet. The command will pay the additional fee by decreasing (or perhaps removing) its change output. If the change output is not big enough to cover the increased fee, the command will currently fail instead of adding new inputs to compensate. (A future implementation could improve this.) The command will fail if the wallet or mempool contains a transaction that spends one of T's outputs. By default, the new fee will be calculated automatically using estimatesmartfee. The user can specify a confirmation target for estimatesmartfee. Alternatively, the user can specify totalFee, or use RPC settxfee to set a higher fee rate. At a minimum, the new fee rate must be high enough to pay an additional new relay fee (incrementalfee returned by getnetworkinfo) to enter the node's mempool.

Arguments

• txid
  string
  The txid to be bumped
• options
  optionalobject
  { "confTarget" (numeric, optional) Confirmation target (in blocks) "totalFee" (numeric, optional) Total fee (NOT feerate) to pay, in satoshis. In rare cases, the actual fee paid might be slightly higher than the specified totalFee if the tx change output has to be removed because it is too close to the dust threshold. "replaceable" (boolean, optional, default true) Whether the new transaction should still be marked bip-125 replaceable. If true, the sequence numbers in the transaction will be left unchanged from the original. If false, any input sequence numbers in the original transaction that were less than 0xfffffffe will be increased to 0xfffffffe so the new transaction will not be explicitly bip-125 replaceable (though it may still be replaceable in practice, for example if it has unconfirmed ancestors which are replaceable). "estimate_mode" (string, optional, default=UNSET) The fee estimate mode, must be one of: "UNSET" "ECONOMICAL" "CONSERVATIVE" }

Returns

{
"txid":    "value",   (string)  The id of the new transaction
"origfee":  n,         (numeric) Fee of the replaced transaction

Note that if your wallet contains keys which are not derived from your HD seed (e.g. imported keys), these are not covered by only backing up the seed itself, and must be backed up too (e.g. ensure you back up the whole dumpfile).

Arguments

getbalance

If account is not specified, returns the server's total available balance. The available balance is what the wallet considers currently spendable, and is thus affected by options which limit spendability such as -spendzeroconfchange. If account is specified (DEPRECATED), returns the balance in the account. Note that the account "" is not the same as leaving the parameter out. The server total may be different to the balance in the default "" account.

Arguments

• account
  optionalstring
  DEPRECATED. This argument will be removed in V0.
• To use this deprecated argument, start bitcoind with -deprecatedrpc=accounts. The account string may be given as a specific account name to find the balance associated with wallet keys in a named account, or as the empty string
  ""
  to find the balance associated with wallet keys not in any named account, or as "*" to find the balance associated with all wallet keys regardless of account. When this option is specified, it calculates the balance in a different way than when it is not specified, and which can count spends twice when there are conflicting pending transactions (such as those created by the bumpfee command), temporarily resulting in low or even negative balances. In general, account balance calculation is not considered reliable and has resulted in confusing outcomes, so it is recommended to avoid passing this argument.

If you have the full public key, you should call importpubkey instead of this. Note: If you import a non-standard raw script in hex form, outputs sending to it will be treated as change, and not show up in many RPCs.

• options
  optionaljson
  { "rescan": <false>, (boolean, optional, default: true) Stating if should rescan the blockchain after all imports } Note: This call can take over an hour to complete if rescan is true, during that time, other rpc calls may report that the imported keys, addresses or scripts exists but related transactions are still missing.
